NGC 2525 is a barred spiral galaxy located in the constellation Puppis.

[4] The galaxy has a bar and two main spiral arms with high surface brightness.

[5] In the centre of the galaxy is predicted to lie a supermassive black hole whose mass is estimated to be between 1.1 and 44 million solar masses, based on the spiral arm pitch angle.

It was discovered on by Kōichi Itagaki on 15 January 2018 at magnitude 16.5,[8] and it was identified spectrographically as a type Ia supernova 10 to 15 days before maximum.

[9] The supernova was also observed by ATLAS on 2018 January 14.5 UT at magnitude 18.1.
